One of the two dogs, a 6-year-old poodle, died while inside the vehicle.
An investigation has revealed that, last Friday, Sharon Mulcahy checked into a hotel and then went to sleep in her room, leaving her dogs inside her car with no water or food.
Temperatures that day reached about 95 degrees.
Police say a hotel employee eventually went outside to check on the canines and realized that one of them had died.
Mulcahy was arrested and the other dog was taken to BARCS.
